Since TurboTax is trying to calculate a tax deferral payment for self-employment tax, then you need to go back into that section of your return and enter that you want 0 self employment tax deferred.
Unfortunately, you may have missed the "SKIP" option when it first started that section and since it was started TurboTax will complete it.
Please complete the following steps to delete the self-employment tax deferral section:
If you go to Tax Tools, then to Tools and then to Federal Review at the top right of the screen, it should open up "Some of your self-employment taxes may be eligible for deferral".
At this point, you can select skip unless you previously selected Continue and entered information in. If so, you will have to continue instead of skip at that point to remove that information.
When you get to the question, "Tell us how much you'd like to defer", you need to enter 0. If you leave it blank, the software defaults to the full amount to be deferred. If you want $0 deferred, you must enter 0 in that box. Then, it will reset to 0 se tax being deferred.
The opportunity to defer se tax on a return was put in place by the CARES ACT, along with the option of employers deferral of depositing the employer portion of payroll taxes until later.
